"The scan revealed that he has a crack to his kneecap and he is definitely out for the rest of the league," Harte is quoted saying by the Ulster Herald.

"The best-case scenario is that he will be out for at least six to eight weeks and it's awful news to hear. First of all for Tiernan himself as he has contracts to fulfil with his work so that is going to have a major impact.

"He has worked so hard to get back to full fitness after his hand injury last season and he is very unlucky for this to happen just as he was back to that level he wanted to be at. It goes without saying that it is a major blow for Tyrone as he is a serious, serious operator for us, one of our key players.

"It takes the shine out of our win on Sunday but, as I said earlier, it's a bigger blow to Tiernan personally."
